ILPRVEMEN T IN CHAMFERING-MACB'INR The Schedule referred to in thesellanera-Patent and making part of the sama.

To all whom "it ma/yconcern:

Be it known that we, BENJAMIN F. MATTOX and SIDNEY GORSON, of ViestRidge, in the county of Mamn, and State of Illinois, have invented a newand improved Machine for Ghamt'ering the Chimes of Barrels, Tubs, andthe like; and we do hereby declare that the following is a full, clear,and exact description thereof, which will enable those skilled in theart to make and use the same, reference being had to the accompanyingdrawing, forming part of this specification.' l

The object of this invention is to provide a simple and effective devicewhereby the chimes. of barrels, tubs, and other similar stave vessels',may be mitred, o r chamiered,so called, in an expeditious and accuratemanner; and

a It consists in the combination and arrangement of the vparts of thedevice, whereby the same is operated without gearing.

The drawing represents a side view of our invention,

also showing, in red color, a sectional view of the chime of-a barrelbeing cutby the knife.

Aisthe base, or pedestalof the machine, from which rises an upright, B.

The horizontal arm D is provided with a perpendicvnlar part, C, which,with the upright, B, is provided with a series of holes, for the bolts bb, by means of 4which devices the heightof the said arm D is adjusted tosuit' barrels and other stave vessels of diierent heights.

'llie arm D E is not continuous, but jointed, by forming the part E witha tenen-extension, which fits within a corresponding recess in the partD, and is secured in place' thereby pins, c c, or other devices, whichwill admit the adjustability of the parts to different lengths.

d is a clamp, serving to support the part E, by crossing underneath therecess and tenori, the ribs of the clamp catching in horizontal slots inthe sides of the part D.

The revolving arm, I, bears the chamfering-tool, K,

which is simply a dat cntting-plate'of metal, having an eye-lug at eachend.

The upper eye-lug is aihxed to the arm I by means of a pin, and thelower lug is afixed, by means 'of a.

pin, to a perpendicular brace-plate, J, the upper end of which isah'ixed to thearm,.and so arrangedas to bring the cutting-tool at theproper angle for cham fering the chime. c v

The arm isltted to slide in a head, G, so that the radial distance fromthe cutter K audits centre of revolution may be adjusted for barrels ofdierent diameters, a pin, n, or other suitable device, being employed tohold the arm in place.

The head Gis formed with a round extension, e, serving as a centre, orshaft, on which the arm revolves.

A crank-handle, H, is axed to the extension e, above `the arm E, andserves to revolve the arm, and thus actuate the cutter K. 5

The brace-plate J contains several holes, so that the cutter may beadjusted to dii'erent angles.

The drawing-illustrates the manner of operating vthis machine.

We are aware that chamferingmachines have been operated by gearing, butthis forms no part of our invention, and We do not claim it, as thegearing renders a machine heavy and expensive.

We claim as new, and desire to secure by Letters I Witnesses:
